Energy flow units
Function codes 03 (read holding registers) and 04 (read input registers) are the only codes
supported for reading these registers, and function codes for writing holding registers are not
implemented. We recommend that the floating point and long integer registers be read in a
single operation with the number of registers being a multiple of two. If these data are read in
two separate operations, each reading a single 16-bit register, then the value will likely be invalid.
The floating point registers with values in display units are scaled to the same units as are
displayed, but are instantaneous values that are not smoothed. If display smoothing is enabled
(non-zero value entered in the Display TC item in the Display Menu), then the register values
will not agree exactly with the displayed values.
